I. Title – The Effect of Volume on Heart Rate II. Problem/Research question – Your heart rate can be affected and changed using a variety of things. One thing that can cause your heart rate to change is the volume of audio. How does the volume of an audio track affect your heart rate? If the volume of an audio track is increased‚ the number of hearts beats per minute will increase as well. III. Variables – ❖ Independent Variable ➢ The volume of the audio track ❖ Dependent

Enzymes lower the amount of energy needed in a chemical reaction. This happens because enzymes are catalysts‚ so they speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has

concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given because of the Soule molecules found within the given volume. This experiment can also refer to hypo

Does caffeine affect heart rate? Background Information: Caffeine is a bitter white crystalline xanthine alkaloid that acts as a psychoactive stimulant drug. A German chemist‚ Friedrich Ferdinand Runge‚ discovered it in 1819. Plants produce caffeine as an insecticide. It is found in varying quantities in the beans‚ leaves‚ and fruit of over 60 plants‚ where it acts as a natural pesticide that paralyses and kills certain insects feeding on the plants.
